For the characteristics of using ordinary digital camera or mobile phone to capture images, study of the key technologies of image registration and image fusion is conducted. Extracting and matching the feature points with the Harris corner detection algorithm, and filtering the feature points with the quick RANSAC method is proposed. Then the LM algorithm to optimize the transformation matrix, and the Multi-resolution fusion algorithm for image fusion to make the final output images achieve a satisfactory visual effect are used. Finally, the algorithm through experiment and splicing results are verified for satisfaction. © 2012 Springer-Verlag London Limited.

Two novel cation-templated complexes, {(1, 4-PMBP)[Pb4I10] DMF}n(1) {(DBBP)2[Pb5I8Br6]}n(2), (1, 4-PMBP 2Br =1, 1"-[1, 4-phenylene-bis(methylene)]bis-4, 4'-bipyridinium dibromide; DBBP 2Br = N, N'-dibenzyl- 4, 4'-bipyridinium dibromide) have been synthesized via the self-assembly reaction in solution. X-ray crystallography showed that compounds 1 and 2 can be regarded as 1D iodoplumbate examples which contain incomplete cubane subunit directed by π-conjugated dication templates. It is the H-bonds and electrostatic interactions between the organic counter cations and inorganic moieties that contribute the crystal packing. These compounds have been further characterized by IR spectroscopy, UV-Vis spectra, elemental analysis and thermostability properties.

A novel coordinated polymer [HgI2L]2 was synthesized through the reaction of ethanediyl bis(isonicotinate) and HgI2 in mixed MeOH-THF (5:2). The crystal structural analysis indicated that the complex crystallized in the monoclinic space group P21/c, a= 10.8575(10), b = 19.8946(19), c = 8.8408(8), = 95.4690(10), V = 1901.0(3) 3, Z = 4. The complex possessed a novel three-dimensional supramolecular framework formed by hydrogen bonds among repeating [HgI2L]2 dimeric units. Its decomposition process is very simple, and decomposition with an apparently endothermal process takes place at the same time. Copyright © Taylor & Francis Group, LLC.

Cation-templated self-assembly of 1,3-bis(4-methylpyridine)alkane cation with AgBr or AgI was studied and two new complexes were obtained: {(bmpp)[Ag2Br4]}n (1) and {(bmpp)[Ag4I6]}n (2) [bmpp = 1,3-bis(4-methylpyridine)alkane cation]. Compounds 1–2 were characterized by elemental analysis, IR, TG, and X-ray crystallography. The two compounds have 1D chain structure. Furthermore, photocatalytic properties at ambient temperature were also investigated. Graphical Abstract: We report two new extend supramolecular polymers based on Ag(I) and 1,3-bis(4-methylpyridine)alkane cation. Compounds 1–2 have 1D chain structures. Furthermore, photocatalytic properties at ambient temperature were also investigated.[Figure not available: see fulltext.] © 2015, Springer Science+Business Media New York.

Cation-templated self-assembly of 1,n-bis(4-methylpyridine)alkane cations (n = 3-7) with CuSCN was studied and a series of new polymeric thiocyanate frameworks were obtained: {(bmpp)[Cu2Br2(SCN)2]}n (1), {(bmpt)[Cu2(SCN)4]}n (2), {(bmppt)[Cu2(SCN)4]}n (3), {(bmph)[Cu4(SCN)6]}n (4), {(bmphp)[Cu2(SCN)4]}n (5), (n = 3, bmpp; n = 4, bmpt; n = 5, bmppt; n = 6, bmph; n = 7, bmphp). The structures consist of 1-2D frameworks with the dications trapped within host network cavities. Compounds 1, 2, 3 and 5 possess the infinite two-dimensional polypseudorotaxane anion networks. Compound 4 has a novel 1D chain structure which looks like lotus root. The results demonstrate that the side chain of methyl substituent plays an important role in the fabrication of polypseudorotaxane structures. Furthermore, solid UV-Vis spectra, photoluminescence and photocatalytic properties at ambient temperature were also investigated. © 2015 Elsevier B.V.

Five new haloclusters, namely, {[Tbmpm](MeOH)[Cu3Br6]} (1), {[Tbmpm][Cu2(SCN)5]}n (2), {[Tbmpm][Ag4Br7] }n (3), {[Tbmpm]0.5[Ag2Br2.2(SCN)0.7]}n (4) and {[Tbpm][Cu2(SCN)5]}n (5) [Tbmpm·3Br = 1,3,5-tri(4-methylpyridiniummethyl)-2,4,6-trimethylbenzene tribromide and Tbpm·3Br = 1,3,5-tri(4-methylpyridiniummethyl) benzene tribromide] were synthesized by the cation-templated self-assembly with Cu/AgX (X = Br, I, SCN) in N, N-dimethyl formamide (DMF) and MeOH system. The X-ray crystallography analysis showed that these compounds were all composed of discrete organic cations and halocluster anions. Compound 1 has a trinuclear structure, compound 2 exhibits an anion complex composed of 1D chain and mononuclear structure, compounds 3 and 4 present similar 1D silver cluster. More interesting, compound 5 possesses a rare 2D polypseudorotaxane structure. The H-bonds and electrostatic interactions between the organic counteractions and inorganic moieties also do the contribution to the crystal packing. These compounds were further characterized by IR spectra, UV-Vis, PXRD, and thermal gravimetric analysis (TGA). Their luminescent properties were also investigated in the solid state. © 2014 Elsevier B.V. All rights reserved.
